Solved with 16th October commits on github.

Thanks, Denis

Hello,

I've notice when using evok through a websocket interface, when a input state is changing, evok is sending back values for all the inputs, not only the one that changed...
Anyway to have only the inputs that changed ?

thanks,
Denis

The example seems to be incorrect ;(

Working now with :

[MCP_2] (instead of 1)
i2cbus = 1
address = 0x21

(the RELAY_8] is already used on the base unipi board , so start at RELAY_9)

[RELAY_9]
mcp = 2 (instead of 1)
pin = 7

[RELAY_10]
mcp = 2
pin = 6

[RELAY_11]
mcp = 2
pin = 5

[RELAY_12]
mcp = 2
pin = 4

[RELAY_13]
mcp = 2
pin = 3

[RELAY_14]
mcp = 2
pin = 2

[RELAY_15]
mcp = 2
pin = 1

[RELAY_16]
mcp = 2
pin = 0

Definitely need documentation on extension, UNIPI !!!

Hello,

I'm trying to add a 8-Relay Addon EMO-R8 to a unipi.

I connected it to the I2C RJ11 connector with an external power supply.
Both LEDs (I2C and power) are On.
I did not change the I2C adress on the board (0x21).

I changed the evok/evok/evok.conf file by removing the ';' in front of the example included in the file
…

;
;Example of 8xRelay extension module addon (EMO-R8) on address 0x21
;
[MCP_1]
i2cbus = 1
address = 0x21

[RELAY_8]
mcp = 1
pin = 7

[RELAY_9]
mcp = 1
pin = 6

[RELAY_10]
mcp = 1
pin = 5

[RELAY_11]
mcp = 1
pin = 4

[RELAY_12]
mcp = 1
pin = 3
...

Since then, the web page (127.0.0.1) is not showing any input or output.
Any idea what I did wrong ?

Thanks,
Denis

Javascript + jquery like in :

  				  $.getJSON('http://192.168.1.39/rest/all',function(temp) {
  				  	 $('#SasTemp').html(temp[23].value + '°C');

```});

enable_cors = True
cors_domains = *

nope…
(

Thanks for your answer.

I changed the file to :
enable_cors = true
cors_domains = *

Then I restart ewok (sudo service evok restart)
Still having :

The 'Access-Control-Allow-Origin' header contains the invalid value '"*"'. Origin 'http://localhost:8888' is therefore not allowed access.

I also tried to reboot the PI with no change….

Same problem here, I changed the config file in evok/etc/evok.conf
to
enable_cors = True
cors_domains = "*"

Thanks for your help,

Denis
